Meaningfulness, Statistical Significance, Effect Size, and Power Analysis: A General Discussion with Implications for MANOVA.
Huston, Holly L.
This paper begins with a general discussion of statistical significance, effect size, and power analysis; and concludes by extending the discussion to the multivariate case (MANOVA). Historically, traditional statistical significance testing has guided researchers' thinking about the meaningfulness of their data. The use of significance testing alone in making these decisions has proved problematic. It is likely that less reliance on statistical significance testing, and an increased use of power analysis and effect size estimates in combination could contribute to an overall improvement in the quality of new research produced. The more informed researchers are about the benefits and limitations of statistical significance, effect size, and power analysis, the more likely it is that they will be able to make more sophisticated and useful interpretations about the meaningfulness of research results. One table illustrates the discussion. (Contains 37 references.) (SLD)
